Solved: Re: How to Group Consecutive Datetimes

JDR100 · ‎10-03-2023

I have a series of date times.

I want to group consecutive datetimes where there is a maximum of 10 minutes between a period.

I can easily find the time diff between consectuve times by adding index and subtracting. The challenge is from there to add a column to group these by.

Hi @JDR100 ,
you can add a column where you check if the calculated time is larger than your threshold and if so, return the index else return null. This will return a table with a number in it whenever a new group must be created.
Then check that new column and fill down values. That will fill down the index value and you can then group on it.
